REACTOR FOR AMMONIUM DINITRAMIDE-BASED LIQUID MONO-PROPELLANTS, AND THRUSTER INCLUDING THE REACTOR

摘要

The present invention relates to a reactor for the decomposition of ammonium dinitramide-based liquid monopropellants into hot, combustible gases for combustion in a combustion chamber, and a rocket engine or thruster comprising such reactor, wherein the reactor comprises a heat bed exhibiting catalytic activity.

主权项

1. A reactor for decomposition of a liquid ammonium dinitramide-based monopropellant into hot, combustible gases, comprising a hollow body of a thermally conductive, heat resistant metallic material provided with, from the upstream end;
an injector; a heat bed; a heat bed retainer (27); a catalyst bed of porous catalyst pellets which are heat resistant up to a temperature of at least 1000° C., and; a catalyst bed retainer,wherein the heat bed comprises a heat bed material exhibiting catalytic activity, which material is formed from non-porous or low-porous high-temperature-resistant ceramic and/or metallic materials, coated with a catalytically active noble metal, and wherein the heat bed retainer exhibits flanges extending upstream into the heat bed and/or downstream into the catalyst bed.
